Router setup with a gamer in house

I am starting to build out my home network. My step dad does a lot of gaming and relies on fast internet. I want to switch out our router with a topton mini pc running opn sense. He wants to get a better and faster Asus gaming router. Is the speed increase on one of these "gaming routers" really that much? And is there some ways to compromise? I dont need extremely fast internet but i of course like it, but i would sacrifice some speed for security and self host features.
